Ajax Post and Plus Sign ( + ) -- How to Encode

AJAX POST and Plus Sign ( + ) -- How to Encode?

Use encodeURIComponent() in JS and in PHP you should receive the correct values.

Note: When you access $_GET, $_POST or $_REQUEST in PHP, you are retrieving values that have already been decoded.

Example:

In your JS:

// url encode your string
var string = encodeURIComponent('+'); // "%2B"
// send it to your server
window.location = 'http://example.com/?string='+string; // http://example.com/?string=%2B

On your server:

echo $_GET['string']; // "+"

It is only the raw HTTP request that contains the url encoded data.

For a GET request you can retrieve this from the URI. $_SERVER['REQUEST_URI'] or $_SERVER['QUERY_STRING']. For a urlencoded POST, file_get_contents('php://stdin')

NB:

decode() only works for single byte encoded characters. It will not work for the full UTF-8 range.

eg:

text = "\u0100"; // Ā
// incorrect
escape(text); // %u0100 
// correct
encodeURIComponent(text); // "%C4%80"

Note: "%C4%80" is equivalent to: escape('\xc4\x80')

Which is the byte sequence (\xc4\x80) that represents Ā in UTF-8. So if you use encodeURIComponent() your server side must know that it is receiving UTF-8. Otherwise PHP will mangle the encoding.

URL Encode a string in jQuery for an AJAX request

Try encodeURIComponent.

Encodes a Uniform Resource Identifier (URI) component by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character (will only be four escape sequences for characters composed of two "surrogate" characters).

Example:

var encoded = encodeURIComponent(str);

ajax - Why jquery replaces + with a space ( )?

In some GET and POST requests (most likely in the URL, or via a form), spaces are encoded as "+" (plus) symbols before they are passed to the server. You can see this behaviour if you do a normal GET request - you will see something like google.com?q=test+example If you want to pass a plus symbol via an ajax GET/POST request, you need to "urlencode" it. The URL encoded value for + is %2B.

Also note:

The javascript encodeURIComponent() function can be used, as answered in:

AJAX POST and Plus Sign ( + ) -- How to Encode?

why replaced plus in string by space

When using $.ajax, use an object rather than a string with the data: option. Then jQuery will URL-encode it properly:

data: { data: data },

If you really want to pass a string, you should use encodeURIComponent on any values that might contain special characters:

data: 'data=' + encodeURIComponent(data),

Send plus of minus symbol as a post value using AJAX

The problem is that you need to encode your value for use in a url:

data:"BloodGroup="+$("#bloodGroup").val(),

If you don't encode the value, a + will be come a space when the value is decoded on the server.

You can have jQuery do that automatically:

data: { 'BloodGroup': $("#bloodGroup").val() },

If you want to encode it manually (when you are not using jQuery for example), you can use:

data: "BloodGroup=" + encodeURIComponent($("#bloodGroup").val()),

Ajax POST method converts my + value in a string to why?

Use the encodeURIComponent() function to turn your data in valid encoded data for the request:

xhr.open("POST", url, true);
xhr.send(encodeURIComponent(postdata));

Unable to send '+' through AJAX post?

Use

request.send("sal="+encodeURIComponent(sal));

The + is interpreted as an space on the server side so you need to encode the string first.

AJAX changes content of the string being sent

You have to change it like this (use encodeURIComponent() on each element):

xmlhttp.open("POST", "/note.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded; charset=UTF-8");
console.log(" >>>> " + note  + " " + noteHTML);
xmlhttp.send("what=edit¬e=" + encodeURIComponent(note) + "¬eHTML=" + encodeURIComponent(noteHTML) + "¬eIdx=" + encodeURIComponent(noteIdx));

Jquery ajax call with '+' sign

azione = escape(String(azione));

should be

azione = encodeURIComponent(String(azione));

or simply

azione = encodeURIComponent(azione);
